"Do you like it, slave?" As she snuggled back into Katherine's warm embrace, Susan laughed. "Although I do look forward to amusing myself with it, I cannot take all the credit. You see, the frame was actually your daughter's idea."

"M-M-Mistress?" Stunned by the revelation, Cathy turned to see both women laughing at her. A part of her wanted to cry at the shame of it all, but there was also a part of her that felt obscenely proud of her little girl. It was only minutes ago that she'd been rudely awakened to the physical maturity of her daughter, and now she was finding a depth of intellectual and psychological growth to match.

Where had the time gone?

Katherine giggled at her mother's reaction, proving that there was still a cheerful teenager behind her oh-so-adult façade. Gently, she turned her partner's head and shared a quick, but passionate kiss. As she turned back to face her slave, she batted her eyelashes and pursed her lips in a seductive pout.

"Daddy," she whined, "could you make us a frame for hanging mommy upside down? I'd really like to whip her pretty pussy, and that would really make things easier for everyone!"

Susan laughed at the encore performance of Katherine's original plea, remembering how amused Glen had been -- and how indulgent. "Our Katherine put on quite a show that night, Cathy dear. What really convinced Glen to commission our new toy, though, was something your sister said."

Her head now resting on Katherine's shoulder, Susan spread her legs for the slender fingers that were so expertly fondling her clit. "I don't remember the exact words," she continued, "but it had something to do with sticking a candle in your cunt so she and Glen could share a romantic dinner."

Her face red with shame, Cathy lowered her head and choked back a quiet sob. While she saw nothing strange in being proud of her daughter's perverted maturity, it was still hard NOT to feel jealous of her younger sibling. "Thank you, Miss Susan. Thank you, Miss Katherine. Thank you for . . . for helping me to serve you better." As always, succumbing to the power of her two other Mistresses helped banish those feelings of jealousy.......(cont)
